the principle of simplified EIA of construction projects in the region. In terms of land, linked to the implementation of urban and rural construction land increase and decrease, replacement indicators for priority areas project. Charges, into the projects of water, electricity, administrative charges and preferential policies. In the area of taxation, and settled in areas of industry and its production company, within 5 years after the completion of fiscal incentives to enterprises. In terms of financing, integration of land, tax, financial and other resources, and construct Government credit + business credit credit system, establishment of marketization, commercialization and modernization of the investment and financing platform; effective Bank-enterprise docking, encourages private capital into the Park, to raise industry development fund. 5, optimize the environment and service industries. To create policy lowlands, Highlands, integrity of service land, development land as the goal, to optimize the area under development environment. All administrative law enforcement departments to appoint a full-time personnel stationed in areas dedicated to coordinating and solving problems associated with businesses in this sector. When there are substantial issues, sector leaders arranged to personally intervene, in-person, in-person push tangible area building a green light, easy line. To further reduce and standardize administrative examination and approval items, simplify examination and approval links, improve efficiency; according to the .Since the educational practice of the mass line of the party, himself seriously in the education, practical control central eight rules and opposing the four winds and practicing three Suns, and check the spirit of Jiao Yulu, ideology, solicit opinions based on outstanding problems checked swing, careful analysis and reflection. Will now check report is as follows: first, adherence to the partys political discipline, eight in the central provision, change the style of the basic situation of 1, in compliance with the partys political disciplines. Conscientiously abide by the partys political discipline, abide by the Constitution and the rules and regulations of the party, in the political, ideological and maintain highly consistent with the CPC Central Committee on the action, there is no violation of the partys political discipline problems. 2, in the implementation of the central authorities of the eight provisions. Improving research, improving research methods, but there are less grass-roots units, primary first-hand an inadequate grasp of the problem, which is to be strengthened in the future. Second, construction, strictly in accordance with the provisions to streamline and improve the quality of meetings of the Conference. Third, streamlining file briefs, culture involves all aspects of propaganda and ideology, sometimes due to the practical needs of invention notifications, this area needs further中交地产青岛城阳夏庄项目 悬挑式卸料平台专项施工方案A2 施 工 方 案 报 审 表工程名称：中交地产青岛城阳夏庄项目 编号：致：中交地产青岛城阳置业有限公司（建设监理单位）我方已根据现场实际情况完成了 中交地产项目二期工程悬挑式卸料平台施工方案 的编制工作,并经我单位审查批准，现上报请予以审查。 附件：中交地产项目二期工程悬挑式卸料平台专项施工方案 承包单位(章)： 项目经理:日 期：（建设单位)专业监理工程师审查意见： （建设单位)专业监理工程师:日 期:（建设单位）总监理工程师审核意见: (建设单位）项目监理机构（章）：（建设单位）总监理工程师：日 期：发包人指定专人负责协调施工中的有关事宜，并监督施工进度、安全与文明施工。发包人对承包人施工中违规操作有权做好处理决定或经济处罚。streamlining. Four are standard visits, except as required to participate in training, no other activity. Five is to improve news reporting, for propaganda work strictly according to the regulations. Six is strictly your presentation published strictly according to the regulations. Seven is strictly thrift, required the use of vehicles and office space and corporate hospitality. 3, change the style. Propaganda and ideological work of the new situation and new requirements of the new tasks, had done a lot of fruitful work, has made many achievements, but further closer to the grass roots, close to reality, close to the masses and also inadequate innovation must continue to improve. Second, the four winds some outstanding issues 1, oppose formalism. One theory is that he didnt, with less close contact. Theoretical study of consciousness is not high enough, system performance is not strong enough; more passive learning, active learning few generalities and learn more, delving into less. Especially based on rational thinking on major issues, applying theory to guide the work done is not good enough, not really understand and grasp the spirit and essence of the scientific Outlook on development, did not truly achieve mastery, to apply, to a certain extent, affect the development and implementation of ideas and initiatives. Second, work arrangements, and less supervision. Propaganda and ideological work is the objective, which needs to keep the continuity efforts deployed, but stressed in the work time, less supervision. For example, color weekends in the summer theatrical activities, city square performances, urging townships, communities and rural areas shows the implementation is inadequate, insufficient cultural an educational role to play. Third base enough, master grass-less real. Propaganda and ideological work in the new situation of characteristics and regularity of enough, deep enough for grass-roots public opinion Dynamics survey, for grass-roots typically drive less. For example, rural culture team active, . Im not actively take the initiative to take up, the lack of spirit of daring to, resulting in some job had a lot of power, but no tangible results. Third, innovation, lack of motivation. Emancipation did not end, innovation does not exist. In practical work, not your head, previous work experience, lack of innovation initiatives, study on the characteristics of propaganda and ideological work under the new situation through, grip on grassroots ideological trends and changes are not deep, to promote new initiatives and explore new methods of ideological and cultural work is not much, and some lack of relevance and timeliness. 4, discipline, lowering, and hard work are lacking. While working and enterprising spirit down. No real solution to treat yourself right, correctly treat past honors, their complacency, and work to see their scores more, less checking his own shortcomings, like to listen to the praise, satisfied face, online promotion, there are typical, and lack of high standards and strict requirements, the effect is real. Second hard drive less.
